. lowing is a specification.

' This invention relates to a process ing tltanlum oxid from rutile or other titanlferous ores, preferably from those with.

.a comparatively high titanium oxid content.

In carrying out my process I may proceed in the following illustrative manner: A quantity of finely powdered rutile, preferably of about 120 mesh is exposed to aheat. of about 125 centigrade or above,

preferably 150 centigrade, in the presence of chlorin gas, thusforlrjing the chlorid of titanium, in a volatilized condition, which is then passed into a boiling solution of glucose, whereby the oxid of titanium is formed, leaving as a by-producta solution of glutaric acid which is valuable for certain commercial purposes. The oxid of titanium is then filtered, washed and dried.

The process-may be performed in a continuous manner by keeping theglucose in the solution in slight excess, and continuing the operation until a nearly saturated solution of the glutaricacid is obtained.

Ilmenite or other titaniferous ore 'may be used in place of rutile, but I prefer .to

use the latter on account of its much higher titanium oxid content. I may use a solution of fructose or other mono-saccharosesin place of glucose although I prefer glucose on account of its lesser cost.

7 While it is preferable to use a finely powderedore, it is possible to carry on, the operation with ores in a coarser form.

The solution of glucose or other monosaccharose may be under the boiling point, although the operation is expedited by using it at the boiling point or over.

1. Theprocess of making titanium oxid which consists of exposing finely'powdered titaniferous ore to a high heat in thepresence of chlorin gas, and passing the vola-' tilizedtitanium chlorid into a solution of glucose, thus forming titanimn'oXid, and.

then ifiltering, washing and drying this product so as to form a fine dry powder.

3. The process of making titanium. oxid which consists of exposing powdered titanlferous ore to a temperature of 125 0.01 more in the presence of 'chlorin gas, thus forming volatilized titanium chlorid which is then passed into a solution of glucose, whereby tltamum oxid is formed, and then filtering, washing and drying this product so as toform a fine, dry powder.

4. The process of making titanium oxid which comprises heating powdered titanif erons ore to a temperature of 125 C. or. over in the presence of chlorin gas, thus forming vo'latilized titanium chlorid, which is then passed into a solution of one of themono-saccharoses whereby titanium oxid i is formed; and then filtering, washing and drying the product so as to form a fine, dry

powder.

5. The process of making titanium oxid in a continuous manner which. comprises heating powdered titaniferous ore to a temperature of 125 C. or over, in the presence of chlorin gas, thus forming. the chlorid of titanium-in a volatilized condition, and then passing the volatilized chlorid of titanium into'a boiling solution of glucose, whereby the oxid of titanium is formed and in keeping the glucose in the solution in slight excess, and. continuing the operation until a nearly saturated solution of glutarlc acid.
